Procedure of putting the heater into operation:
1.
Check the water main and wiring. Check proper placement of operating and safety thermostat
sensors. The sensors must be inserted all the way in; first the operating and then the safety
thermostat.
2.
Open the hot water valve on the combination faucet.
3.
Open the cold water inlet valve to the heater.
4.
As soon as the water starts running through the hot water valve, the heater is filled, and the valve
can be closed.
5.
In case of leakage (of flange lid), we recommend that the flange lid bolts are fastened.
6.
Screw down the electric installation guard.
7.
When hot service water is heated by electric energy, switch on the power supply.
8.
When commencing operation, flush the heater until the cloudiness in the water is gone.
9.
Make sure to fill in properly the warranty certificate.

PUTTING OUT OF SERVICE, DISCHARGE
If the hot water heater is put out of service for a longer time, or if it is not going to be used it
has to be drained and disconnected from the electric supply network. The switch for the supply
lead or the fuse cut-outs have to be shut off.
At places with permanent risk of frost the hot water heater must be drained before the cold
season starts if the appliance remains out of service for several days and if the power supply is
disconnected.
Drainage of service water shall be performed after closing the shut-off valve in the cold water
supply piping (through the discharge valve for safety valve combination), and with simultaneous
opening of all hot water valves of connected fittings (water can be also drained through safety
valve; for that purpose, the safety valve is turned to the "Check" position).
Hot water may
outflow during the drainage!
If there is a risk of frost it has to be considered that not only the
water in the hot water heater and in the hot water piping may get frozen but also the water in
the entire cold water supply piping. It is therefore advisable to drain all fittings and piping that
carry water, up to the part where the house water meter is installed (connection of the house
to water main) which is not jeopardized by frost. When the tank is to be used again, it has to be
filled with water and one needs to make sure that the water flowing out at the
hot water valves
did not contain any bubbles
.

INSPECTION, MAINTENANCE & CARE FOR THE APPLIANCE
During the heating process the water that increases its volume during the heating must visibly
drip off the safety valve outlet (in non-pressurized connection this water drips off the
combination faucet valve). In full heating (about 77
°C) the volumetric water gain is approx. 3 %
of the tank capacity. The function of the safety valve has to be checked regularly. If the safety
valve control knob is lifted or turned to the “Control” position, the water must flow out easily,
without any obstacles, from the safety valve element to the outfall line. In common operation,
such a check needs to be implemented at least once a month, and after each heater shutdown
for more than 5 days.
